Definitions
- the invention relates to a shut-off device for a container for a powdery medium with one in one Drain channel displaceably arranged closure piece.
- a shut-off device for a container for a powdery medium with one in one Drain channel displaceably arranged closure piece.
- Such a shut-off device, the drain channel one first, round section in longitudinal section, is from the GB-PS 203 876 known.
- a sintered material can be numerous Transport or other procedural steps may be necessary which a transfer of a powdered medium from a container into another container is required.
- the type of powdery medium can be of particular importance The importance of controlled treatment of the medium to ensure. This is for example with a toxic, radioactive or particularly valuable medium of Case.
- a build-up of residue before or during the transfer process of particles of the medium in the container to be emptied be avoided, for example, on adherence of Particles of the medium on the inner walls of the to be emptied Container as well as bridging between particles of the medium can be returned.
- the powdery medium also requires that the amount of medium drained from the container can be precisely adjusted by dosing.
- the invention is therefore based on the object of a shut-off device for a container for a powdery medium specify by which in the closed state an exit of the powdery medium from the container and thus a Loss of the medium is safely avoided.
- the Shut-off device in the open state a dosed and Allow residue-free emptying of the medium from the container.
- This task is for a shut-off device of the above Kind solved according to the invention by the drain channel a first, in the longitudinal section round area and one underlying second, conical area includes.
- the first area of the drain channel which is round in longitudinal section is achieved that when opening the shut-off device by moving the closure piece into the drain channel the cross-section for the powdery medium quickly enlarged. This will get the powdery medium when opening the shut-off device quickly and safely into one Flow movement, so that a sticking effect of the powdery medium on the inner wall of the container or the drainage channel as well as bridging and thus a clumping of the powdery medium avoided are.
- the first, longitudinal section of the drainage channel fulfills the function of an acceleration range.
- the closure piece is also to facilitate advantageously rounded at its closing edge.
- the drainage channel is in a particularly advantageous embodiment
- Part of the shut-off device of a ball valve that is in the closed position Condition has a high level of tightness. So there are losses in powdery medium before or after a transfer avoided particularly effectively.
- the ball valve can be one Shut-off valve for the container to be emptied or a shut-off valve for the container to be filled.
- the closure piece advantageously has a coaxially arranged to the drain channel, within the to emptying container extending drive rod.
- This Drive rod is expediently designed such that they are in the closed state of the shut-off device over the edge of the drain channel resting on the closure piece carries the weight of the container, making the container special is sealed tightly and effectively. That’s it Closure piece advantageously conical.
- the shut-off device thus has one the flow profile of the powdery medium to be discharged adapted longitudinal section, so that an outlet of the powder Medium through the drain channel in particular is favored.
- the advantages achieved with the invention are in particular in that through the first round section in longitudinal section and the second, conical one underneath Residue-free emptying in the area of the drainage channel a container and also a targeted dosing of the drained powdery medium is achievable.
- closed Condition such a shut-off device has a high Tightness so that the container is securely closed and an undesirable loss of powdery medium is avoided.
- the shut-off device 1 comprises a on a drive rod 2 arranged locking piece 4. Die Drive rod 2 is arranged inside a container 6, in which there is powdered medium M.
- the Closure piece 4 is slidably disposed in a drain channel 8.
- the drain channel 8 comprises a first, in longitudinal section round area 10 and an underlying second, conical region 12.
- the first region 10, d. H. the entry or acceleration area, and the second area 12, d. H. the exit or metering area, are arranged to each other in such a way that the drain channel 8 is approximately heart-shaped in longitudinal section.
- the closure piece 4 is rounded at its closure edge 14 and conical in the area of its back surface 16 educated.
- the back surface 16 of the closure piece 4 and the inner surface of the first region 10 of the drain channel 4 are parallel to each other in longitudinal section.
- the docking area 18 has a smaller one Cross section on as the maximum cross section of the closure piece 4.
- the drive rod 2 is designed such that they are the weight of the closure piece 4, the container 6 and the medium M located in it. On in this way, the container 6 is sealed, and a unintentional opening of the container 6 is avoided.
- the drain channel 8 comprising the areas 10 and 12 is part the shut-off element 22 of a ball valve 24.
- the ball valve 24 is fixed to a docking ring 20 one - not shown - Mounted container to be filled, so that the filled Container can be sealed tightly and securely by means of the ball valve 24 is.
- the ball valve 24 can also be firmly connected to the container 6, so that a tight Closing the container 6 is guaranteed.
- the container 6 is opened the ball valve 24 arranged on the container to be filled in such a way placed that the closure piece 4 in the drain channel 8th is slidable into it.
- the shut-off device is open 1 is the closure piece 4 in the drain channel 8 moved in ( Figure 2).
